Pyridine-Thiourea Based High Performance Polymers: Synthesis and Characterization

引用

Chinese Journal of Polymer Science 2015年第1期33卷 49-60页

作者： Ghulam waris Humaira Masood Siddiqi Department of Chemistry Quaid-i-Azam University Islamabad Pakistan Department of Chemistry University of SheffieldUK

A novel diamine monomer, pyridine-2, 6-bis（（4-aminophenyl）thioureido）carbonyl（PATC） was synthesized efficiently and polymerized with various aromatic dianhydrides. Consequently, poly（pyridine thiourea-imide）s（PPTIs） with good thermal properties and flame retardancy were fabricated. The structures of PATC and PPTIs were characterized by FTIR, 1H-NMR, 13C-NMR spectroscopy along with elemental analysis, crystallinity, organosolubility, inherent viscosity and gel permeation chromatographic measurements. PPTIs containing C=S, CONH and meta substituted pyridine moieties in the polymer backbone showed amorphous nature and were readily soluble in highly polar organic solvents and even in less polar solvents such as tetrahydrofuran（THF）. Polymers had inherent viscosities in the range of 0.91-1.16 d L/g and molecular weight was found between 68000-77000 g/mol. The electrical properties of the PPTIs were estimated in terms of dielectric constant over a range of frequencies. Their thermal stability was determined by 10% weight loss temperature found in the range of 519-563 °C under inert atmosphere. The glass transition temperature of the polyimides varied between 247 °C and 267 °C. The flame retardant properties of PPTIs were investigated in terms of limiting oxygen index（LOI） which was found in the range of 38.26-39.95. Introduction of thiourea in the polymer backbone is an effective way to improve the thermal stability and flame retardancy. Thus PATC can be considered as an excellent candidate for the synthesis of high performance polymers.

MWCNTs/SWCNTs Nanofluid Thin Film Flow over a Nonlinear Extending Disc: OHAM Solution

引用

Journal of Thermal Science 2019年第1期28卷 115-122页

作者： GOHAR TAZA Gul waris Khan MUHAMMAD Shuaib MUHAMMAD Altaf Khan EBENEZER Bonyah Department of Mathematics University of Peshawar Department of Mathematics City University of Science and Information Technology Higher Education Department Khyber Pukhtunkhwa Department of Mathematics Islamia College Department of Mathematics Kumasi Techniical University

The aim of this research is the improvement towards the consumption of energy in the field of engineering and industry. The efforts have been paid to the enhancement of heat transmission and cooling process through a nanofluid coating of a nonlinear stretching disc. The combination of Water(H2 O) and multiple walled carbon nanotubes(MWCNT)/single walled carbon nanotubes(SWCNT) have been used as a nanofluid. The spreading of a thin nano-layer with variable thickness over a nonlinear and radially stretching surface has been considered. The estimated results of the problem have been accomplished using the Optimal Homotopy Analysis Method(OHAM). The residual errors of the OHAM method have been shown physically and numerically. The important physical parameters of skin friction and Nusselt number have been calculated and discussed. The other embedding parameters like generalized magnetic parameter, Prantl number, nanofluid volume fraction and Eckert number have been intended and discussed. The obtained results have been compared with the Numerical(ND-Solve) method for both sorts of CNTs. The closed agreement of both methods has been achieved.
